Windows 7: Computer suddenly claims my Windows is invalid

Since then I have steadily upgraded it, I changed the GPU, the RAM, motherboard broke and was replaced and also a new CPU fitted.

Recently I have bought a new SSD, a Crucial M500 240Gb SSD and installed windows onto it, reformatted my older Seagate HHD and set everything up. Activated Windows and everything is fine.... until today I get an error pop up in my face saying my Windows is not valid..... I should think it bloody well is, having had it for two years this better not be some money grabbing scheme trying to force me into buying a new copy of Windows.

From what I have read, if I click the validate button and download the tool I risk having significant functionality removed and/or extremely inconvenient messages nagging me, simply because Microsoft have ballsed up an update or something.

I am currently using my mobile phone, a HTC One X Plus as a network adapter using USB Tethering and network pass-through to connect to my Landlord's Wi-Fi until Virgin install their modem on Friday, so I'm hoping that shouldn't be blocking any updates that would otherwise resolve this.

There are no problems showing in your report - you appear to be properly activated and validated.
What happens if you attempt validation on this page? www.microsoft.com/genuine/validate using Internet Explorer ?

Sundry external drives attached to other computers on the local network
1TB on the Lenovo Internet Speed as much as I can get - usually on a dongle, so <1Mb/s Antivirus MSE Browser IE11/Chrome/FF(if I must)

That page is what the pop up leads me too, but I have been unwilling to go through with it after reading up on line how it can quite often given incorrect answers and thus causing me grief. If I wasn't being prompted by a window saying my Windows is not valid I would be more than happy to go through with that process.

I am hoping that the reason this has occurred is due to certain Windows security updates failing to download/install and might be caused due to my connection being via Network Pass-through using an Android device. This issue being caused by failed updates or without updates to Windows was also mentioned online.

If you are seeing non-genuine messages, but the tend to come and go of their own accord, this is probably due to a race condition - such conditions are usually caused either by over-active AV, or by malware.

Please download and install Malwarebytes Anti-malware (free version) from http://www.malwarebytes.org/products/malwarebytes_free/ - UNtick 'Enable free trial of MBAM PRO' at the end of the installation - and update it, then run a full scan in your main account, and Quick scans in any other user accounts.
